Wiring Procedure
Use crimp terminals for wiring; use 3.31 mm ²
–0.13 mm² wire (12-26 AWG):
1. Strip the wire to a length of 7±0.5mm (0.270
–0.300“).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure a proper connection.
4. Tighten enough to keep the wire from pulling free.
Wiring Guidelines
Use separate wiring ducts for each of the following groups:
o
Group 1: Low voltage I/O and supply lines, communication lines.
o
Group 2: High voltage Lines, Low voltage noisy lines like motor driver outputs.
Separate these groups by at least 10cm (4"). If this is not possible, cross the ducts at a 90˚angle.
For proper system operation, all 0V points in the system should be connected to the system 0V
supply rail.
Allow for voltage drop and noise interference with input lines used over an extended distance.
Use wire that is properly sized for the load.
Earthing the product
To maximize system performance, avoid electromagnetic interference as follows:
Use a metal cabinet.
Connect the 0V terminal directly to the earth ground of the system.
Use the shortest, less than 1m (3.3 ft.) and thickest, 2.08mm² (14AWG) min, wires possible.
Inputs
1.
All the products comprise I0-I5; these digital inputs are arranged in a single group. Via wiring,
the entire group may be set to either pnp or npn.
2.
The following information concerns JZ20-R10/JZ20-J-R10 and JZ20-R16/JZ20-J-R16:
I0 and I1 can function as high-speed counters or as normal digital inputs.
3.
The following information concerns JZ20-J-R16HS:
I0, I1, and I4 can function as high-speed counters, as part of a shaft-encoder, or as
normal digital inputs.
I2, I3, and I5 can function as either counter reset, as part of a shaft-encoder, or as
normal digital inputs.
If I0, I1, I4 are set as high-speed counters (without reset), I2, I3, I5 can function as normal
digital inputs.
4.
The following information concerns JZ20-R16/JZ20-J-R16 and JZ20-J-R16HS in addition to
I0-I5, these comprise the following:
I6 and I7 may be wired as either digital or analog inputs. These may be wired as either:
npn digital inputs
pnp digital inputs
analog (voltage) inputs
In addition, one input may be wired as a pnp input, while the other is wired as an analog input.
Note that if one input is wired as an npn input, the other may not be wired as an analog input.
5.
The following information concerns JZ20-R16/JZ20-J-R16 and JZ20-J-R16HS:
AN0 and AN1 are analog (current) inputs.
